A 10-m retaining wall is shown in figure A, determine: a. The active thrust on the wall due to soil and water b. The active thrust on the wall due to soil only [dry] c. The increase in force on the wall if the soil is fully saturated with rainwater.
Figure A
Gs = 2.65
-e = 0.50
w = 10%
= 20 deg
Transcribed Image Text:Figure A Gs = 2.65 -e = 0.50 w = 10% = 20 deg
